This is very simple math. Needs no explanation, however this site requires an explanation for something so simple.<span />
Answer:
r = P -t -s
Step-by-step explanation:
This is a one-step linear equation in r. Subtract the terms that don't contain r:
P = r + t + s . . . . . . . . . . given
The terms on the right that don't include r are (t+s). We want to subtract that to get r by itself.
P -(t+s) = r +(t+s) -(t+s) . . . subtract (t+s)
P -t -s = r . . . . . . . . . . . . . . simplify
r = P - t - s
Answer:
x=499.83
y=500.16
Step-by-step explanation:
We can solve this problem with a system of equations:
The total quantity of Nerds in the box:
(1)
The amount of Nerds left in the box:
The number of portions Mrs. Konings has taken:
The amount of Nerds left in the box decreases by a third each time she dumps out a portion:
(2)
Substituting (2) in (1):
(3) This is the equation
Let's find :
(4)
Now let's find by substituting (4) in (2):
(5)
Answer:
The value of your equation would be 371/30
Step-by-step explanation:
Given tanθ=8/15 - -(1)
sec^2θ
= 1+tan^2θ
= 1+(8/15)^2
= 1+64/225
= 225+64/225
= 289/225
=17^2+15^2
Now, secθ =
= 17/15
Cosθ = 15/17 - -(2)
Value of sinθ+cosθ/cosθ(1-cosθ)
Dividing numerator and denominator by cosθ, we get
= sinθ+cosθ/cosθ/cosθ(1-cosθ)/cosθ
= (sinθ/cosθ+cosθ/cosθ)/(1-cosθ)
= tanθ - 1/1-cosθ
= 8/15 + 1/1-15/17
= 8+15/15/17-15/17
= 23/15/2/17
= 23/15 x 17/2
= 371/30
Hope this helps!
-18 u just need to use the calculator lol
